Total number of elements in a specified dimension of an Array in C#

CsharpServer Side ProgrammingProgramming

To get the total number of elements in a specified dimension of an array, the code is as follows −

Example

 Live Demo

using System;
public class Demo {
   public static void Main() {
      string[] products = new string[] { "Andy", "Mark", "Gary", "Andre"};
      Console.WriteLine("One or more name begins with 'A'? = {0}",
      Array.Exists(products, ele => ele.StartsWith("A")));
      Console.WriteLine("Is the array having fixed size? = " + products.IsFixedSize);
      Console.WriteLine("Is the array read only? = " + products.IsReadOnly);
      Console.WriteLine("Is the array synchronized? = " + products.IsSynchronized);
      Console.WriteLine("Index of the 1st element = "+products.GetLowerBound(0));
      Console.WriteLine("Index of the last element = "+products.GetUpperBound(0));
      Console.WriteLine("GetLongLength(0) = "+products.GetLongLength(0));
   }
}

Output

This will produce the following output −

One or more name begins with 'A'? = True
Is the array having fixed size? = True
Is the array read only? = False
Is the array synchronized? = False
Index of the 1st element = 0
Index of the last element = 3
GetLongLength(0) = 4

Let us now see another example −

Example

 Live Demo

using System;
public class Demo {
   public static void Main() {
      string[,, ] stdNames = new string[,, ] {
         { { "John", "Gary" },
            { "Jacob", "Harry" } },
         { { "Kevin", "Ryan" },
            { "David", "Mark" } },};
         Console.WriteLine("Is the array having fixed size? = " + stdNames.IsFixedSize);
         Console.WriteLine("Is the array read only? = " + stdNames.IsReadOnly);
         Console.WriteLine("Is the array synchronized? = " + stdNames.IsSynchronized);
         Console.WriteLine("Index of the 1st element = "+stdNames.GetLowerBound(0));
         Console.WriteLine("Index of the last element = "+stdNames.GetUpperBound(0));
         Console.WriteLine("GetLongLength(0) = "+stdNames.GetLongLength(0));
         Console.WriteLine("GetLongLength(0) = "+stdNames.GetLongLength(1));
   }
}

Output

This will produce the following output −

Is the array having fixed size? = True
Is the array read only? = False
Is the array synchronized? = False
Index of the 1st element = 0
Index of the last element = 1
GetLongLength(0) = 2
GetLongLength(0) = 2
